[MC8090]SMS-STATUS-REPORT support

IoT Modules MC/EM Series
1

Hi,

I’d like to clarify the reason why “+CMS ERROR: 303” which means "operation not supported " according to 3GPP TS 27.005 is returned.

AT log in my testing is follows.

at+cnmi=2,1,0,0,0
OK
at+cnmi=2,1,0,1,0
+CMS ERROR: 303

If I enable SMS-STATUS-REPORT is routed to the TE, +CMS ERROR:303 was returned.
I think this is caused by MC8090 or SIM card.

I’d like to know MC8090 can support SMS-STATUS-REPORT routed to TE.

BTW,if anyone can enable =1 correctly , it means my SIM card does not support SMS-STATUS-REPORT.

Thank you.

What firmware version is on the MC8090? (ATI3)
Have you tried with AT+CNMI=0,1,0,1,0 instead?
I’m 95% certain that I’ve tried AT+CNMI=0,1,0,1,0 on SL8090 which is basically the same thing, and that it worked then.
